There has been a great rise in interest about probiotics and related products with the wide range of benefits that it can render. However, research suggests that a minimum colony forming unit (CFU) of the probiotic strains is needed in order to provide the desired beneficial traits. The poor survival of the bacteria as indicated by several reports is a major question to that effect. Several environmental factors like the oxygen toxicity (as most of the probiotic strains are microaerophilic in nature) challenges its existence during processing and storage. Also, the passage through the gastro-intestinal tract offers a variety of extreme conditions like low pH that reduces a significant proportion of the probiotic population. So, efforts are being carried out to develop and design effective modes of administration of the probiotics to the recipients in forms that are resistant to the different survival challenges and increase its overall viability. Microencapsulation is one of the latest technologies that can increase the survival rate of the probiotic bacteria. [Read more…]
